Hi all- Rick from San Francisco here. Heading off to Europe on vacation soon. Unfortunately can't make it to TrialGP Andorra or Lourdes. I am dying to see some professional trials practice/ riding. I'm going to be in and around Barcelona June 30-July 7, then driving from Barcelona up through Andorra and west over the Pyrenees from July 11 to 13. Does anyone have any suggestions on places I should check out? Obviously anything specific would be great, but I will happily drive somewhere even if there is only a chance I might catch someone. Towns, parks, streets, gps coordinates- anything would be much appreciated. Thanks!

Thanks very much to everyone who responded to my post. At this point, while it seems like it might be possible, I am leaning towards not trying to buy a bike in EU and just paying a bit more for one with a CA OHV sticker when I get back. Cheers- Rick

Hi All, I have been thinking about something - I would appreciate if you could tell me all the reasons it can't work. Quick background - I am a newbie, have been riding an electric trials bike for about a year (awesome as I can ride it in public parks/woods but limited performance vs a gas bike), never owned a gas trials bike before. I owned some dirt bikes when I was younger so I can take them apart and put them back together without too many parts left over. Used trials bikes in Northern California tend to have a few things in common: they seem pretty hard to find, they are nearly as expensive as new ones, and many of them have a cute little seat and two chrome shocks on the back... Given this, I had an idea. I'm taking the wife to Europe this summer and we will be driving around Spain for a few weeks. After looking for just a few minutes, I am already salivating at the range and prices of used trials bikes for sale there. By very rough guess it looks like bikes at least a few years old are $1k and maybe even $2k cheaper there. In addition, it seems like I could get just about any bike I wanted within a model year or two without much problem.... The potential problems: 1) Getting it home. I was thinking I could take it apart and put the engine in a box as excess luggage and the remainder in a bicycle box and take it home on the plane with me. Crazy idea? Possible? If this isn't feasible perhaps I could have it shipped somehow but I don't know by whom or what the cost would be. Any thoughts? The best bikes I have seen are from private sellers (just like here), but I suppose I could buy from a dealer if that would facilitate transport. 2) I live in California and I will end up with what I believe will be an illegal immigrant bike. I suspect this will prevent me from getting a red or green sticker and therefore preclude me from riding on public lands. From SF we have to drive a few hours anyway to get to an OHV park; I believe there are some privately owned trials areas not much farther than that. Would I be able to ride it on a "commercial" private trials area or would the bike be deported or confiscated? I am not sure how titles work over there but since I won't be trying to register it I don't think it matters? Also, while I don't have plans to compete, I suppose I might want to in the future at some point. Would it be enough to just install whatever required equipment (e.g. spark arrestor) or would I be precluded from competing on such a bike? In any case, any experience, guidance, or ideas would be much appreciated! Rick

Thanks. My plan is to locate the battery disconnect above the battery and use it only as a safety shutoff when the bike is not being used- it will only be turned on or off when the key is off.

Ok, I think I've got it. Attached is a schematic that started as the stock drawing from Kelly that I modified - my edits are shown in red. Could I trouble you to take a quick look and see whether it looks right? Thanks again for the help.

Ok, I decided against the "clutch" and I am working on the actual wiring design since the controller will get here next week. I do want to put in a battery disconnect of the sort that might be used on a boat or an RV- the one I got can handle the power of my system. My question is this: while the main contactor is on the (+) side of the power circuit, it seems to make sense to me to put the battery disconnect on the (-) side. Is this correct? Also, I am unsure whether I need a precharge resistor in parallel with the battery disconnect switch. I believe not as this would seem to leak current across the switch which would prevent the complete disconnection of the battery. Can you tell me if my logic is wrong - perhaps I need some other component such as a cap in series with the switch instead to protect the controller from the power surge?

Thanks very much Gwhy - from reading this and other forums it seems you know more about this stuff than just about anybody. Since I am still in the design phase, perhaps I could try one more on you? My understanding is the Electric Motion EM 5.7 has a "clutch" which is really just an on-off switch on a lever which can be "popped" with the throttle in a partially open position. I believe this would switch something different than the kill switch - maybe using a separate relay or something... do you have any thoughts on this and/or how this functionality might best be set up with the Kelly KDS? Thanks!

Hi All- Great thread. I have had a 2016 20R for a few months and I recently upgraded the battery to a 14s10p pack of NCR18650 PFs w/ a 50A continuous/125A peak BMS which is awesome. I have been suffering with the stock throttle and controller, however, and I have big hopes for improvement with my recently ordered KDS72200E controller and Domino 5 wire throttle. This thread will be really helpful when I go to install these new components. Now my questions: 1) Any suggestion on using the 4th and 5th wires from the Domino? My understanding is they are a switch - I wonder if I should use them to turn off the controller when the throttle is closed? 2) Regarding the main fuse between the battery and the relay, I am not clear on what I should be using. Would I want to go with 125A or perhaps a big heavier? Thanks again to everyone who has contributed to this thread - I will share my experience once I have some.
